* In the disubsitituted cyclohexane 1 it under ring closing reaction via intramolecular SN2 mechanism .
In this reaction the back side attack is possible , to the epoxide is formed easily.
* In the disubsitituted cyclohexane 2 , Both subsituent are in same plane .
In this reaction , when the intermediate is formed , there is no intramolecular SN2 reaction is possible. Because there is no back side attack possible here.
So the epoxide is not formed in the 2 compound.
(ii) On treatment with aqueous sodium hydroxide, disubstitued cyclohexane 1 readily undergoes a ring-closing reaction to...

CH NaOme MeOH CH Compound A Problem 2c Draw the major expected organic product (a) Redraw Compound A as seen in Viewpoint I below left as a Newman projection on the template provided in Problem 2a (below). Hint: Fill in missing Hs ar C2 and C3 to help you get started! (b) Rotate the C2 C3 bond to obtain the...
Organic Chemistry Help! Questions and Exercises 1. In the course of reflux of the triglyceride in a sodium hydroxide solution you will notice a lot of foaming. Explain. What is left behind in the aqueous layer after filtration of the saponification product? The starting material and the product of the saponification reaction have similar melting points. How do you know you actually isolated a new product rather than just recovered the starting material? Give at least two different methods to...
